“…Moreover, they noticed that with the addition of Span 80 and Tween 85 surfactants, smaller droplets of 30 and 18 μm for oil fractions of 30 and 40 % were obtained . Kamlow et al reported an emulsion droplet size of 0–30 μm for sunflower oil emulsion filled κ-carrageenan gels, where they observed flocculated droplets with Tween 20 and well-dispersed droplets with whey protein isolate …”

“…Emulsion gels can be created using several methods; one is to create an emulsion by homogenization and then add the gelling agent . Kamlow et al first created a sunflower oil-based emulsion with either WPI or Tween 20, and then added κ-carrageenan to the emulsion to create emulsion-filled gels. , Another method is to homogenize the κ-carrageenan solution directly with oil to create emulsion gels. This method has been used to create κ-carrageenan emulsion gels with surfactant Span 20, Span 80 and Tween 85, or by adding cross-linker KCl .…”

In this work, κ-carrageenan and olive oil at different oil to κ-carrageenan ratios (OCR) are homogenized to create emulsion gels. Interestingly, confocal imaging shows that the oil droplets are stabilized in the κ-carrageenan-structured gel matrix without using any surfactants. Rheological studies show that the oil droplets enhanced the oscillatory yield stress and the maximum printable height of the emulsion gels. The creation of the emulsion gels with an OCR of 1:9-3:7 led to an improvement in the structural integrity of extrusion printed structures. The emulsion gel with an OCR of 3:7 efficiently encapsulates vitamin C in the aqueous phase and curcumin in the hydrophobic oil phase, enabling the extrusion 3D printing of tablets with varying surface area to volume (SA/V) ratios. The release of vitamin C and curcumin is influenced by the preparation method of printing versus casting and the SA/V ratio of the tablets. The hollow cylinder with the highest SA/V ratio was observed to have the highest vitamin C release, whereas for curcumin, the printed tablets had a higher release compared to the cast tablet. Additionally, through rheo-dissolution experiments, we observe a lower modulus and higher vitamin C release from the 3D-printed disc versus the higher modulus and lower vitamin C release from the cast disc tablet.

“…However, they also acknowledged the necessity for precise control over scaffold dimension variations and viscous composite printing for optimal results. Investigating kappa-carrageenan (kC), Kamlow et al [90] illuminated the potential of 3D printing complex foods with algae-based biopolymers. All formulations could be printed with identical parameters, denoting their structural integrity.…”

The integration of machine learning (ML) with algae‐derived biopolymers in 3D printing is a burgeoning area with the potential to revolutionize various industries. This review article delves into the challenges and advancements in this field, starting with the critical problem it addresses the need for sustainable and efficient additive manufacturing processes. Algae‐based biopolymers, such as alginate and carrageenan, are explored for their viability in 3D printing, highlighting their environmental benefits and technical challenges. The role of ML in enhancing material selection, predictive modeling, and quality control is examined, showcasing how this synergy leads to significant improvements in 3D printing processes. Key findings include the enhanced mechanical properties of algae‐based biopolymers and the optimization of printing parameters through ML algorithms. Examples like the use of Spirulina in creating a range of materials and the application of carrageenan in bone tissue engineering are discussed. The conclusion underscores the transformative impact of combining ML with algae‐based biopolymers in 3D printing, paving the way for innovative, sustainable solutions in additive manufacturing. Despite existing challenges, this integration holds promise for a future of advanced, eco‐friendly manufacturing techniques.
